Technical Description

The ERLO TCA-70BV is a heavy-duty upright drill press designed for high-capacity industrial drilling and tapping operations. It features a drilling and tapping capacity of 2.76 inches (70 mm) on mild steel and supports tapping up to M70. The spindle incorporates a Morse No. 5 taper (MK5) and is powered by a robust 10 HP main motor. The spindle speed ranges from 35 to 1238 RPM across 12 standard speeds at 50 Hz, enabling versatility across different materials and drill sizes. The machine offers six automatic feed rates—from 0.05 to 0.50 inches per revolution—with a head automatic feed rate of approximately 1.1 meters per minute. The spindle stroke measures 11.8 inches (300 mm), with the centerline-to-column distance at 24.8 inches (630 mm). The prismatic column supports a fixed, adjustable headstock and uses hardened, ground steel gears for spindle drive, ensuring durability and precision. The work table has generous dimensions of 40.9 by 23.6 inches (1040 x 600 mm), providing stable support for large workpieces. Additional features include an automatic/electromagnetic feed clutch, a tool ejector system, a coolant system driven by a 0.20 HP pump motor, and low voltage controls for safety. The head displacement motor runs at 750 RPM with 2 HP. The drill press weighs approximately 4674 lbs (2120 kg) and includes essential user controls such as a fine feed handwheel and adjustable depth stop, facilitating precision operation and efficiency in heavy-duty drilling tasks.
